DESK-LOCK.

SPECIFICATION forming part of Letters Patent No. 750,384, dated January26, 1904. Application led June 20, 1902. VSerial No. 112,476. (Nomodel.)

T0 all whom it may concern.-

Be it known that I, LAFAYETTE MOORE, a citizen of the United States,residing at Tuskegee, in the county of Macon and State of `Alabama, haveinvented certain new and useful Improvements in Locking Mechanism forthe Drawers of Desks, Sac.; and I dohereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which. form a part of thisspeciiication.

This invention relates to improvements in the locking mechanism indesks.

It consists, substantially, in the means I employ whereby a singlemotion of a certain part of the desk simultaneously locks the severalother parts, as will be hereinafter fully explained, and pointed outinthe claim.

In the drawings, Figure l, I show a detached view, somewhat enlarged, ofparts of my device. Fig. 2 is a vertical section on line r r, Fig. 4.Fig. 3 is a vertical section on line W W, Fig. 4. Fig. 4 is alongitudinal section on line S S, Fig. 2. Fig. 5 is an isometrica]representation of the desk with the upper portion and a portion of theends cut away to reveal the locking mechanism.

In the lower portion of a cabinet-desk my invention is substantially thesame as in some desks to be found in the trade, consisting of endportions of pedestal form iitted with drawers a Z1 c d.

K represents transverse bars having their front ends suitably joined tothe rear edge of the front bar L, from which they extend rear ward,having their ends suitably fixed to a rear bar or to the back of thedesk M.

At g are represented mortised-out slideways which are fixed in asuitable position to the cross-bar N, which is fastened to the base ofthe desk.

la represents slide-bars iitted to move freely in a vertical position incross-bar N. To these slide-bars are fixed at proper intervalshookformed clasps f of suitable conformation to overlap the edge of therear end of the draw- The upper ends of ers at w when slid down.

the vertical slides are connected by means of a suitable horizontal bare.

At c' are represented spiral springs placed in upper stile Q, Linder thehorizontal bar e, employed to support the slides in their elevatedposition, but in such a manner as to permit them to be depressed to lockthe drawers when closed.

At m are represented sides of the center drawer E, which has a slant atj to rear of the two sides at an angle of thirty degrees, so that theywill move freely on the horizontal bar e.

At j is represented a covering of tin or onesixteenth-inch iron toprevent a wearing of the under side of m by continuous pressing on bare.

By this construction it will be seen that the sliding movement of thecenter drawer E of the desk will operate to depress the horizontal barc, to which the slide-bars are fixed, causing the hooks f,fixed to thevertical sliding' bars, to engage the rear end of the drawers at n tolock them in their closed position, and the forward movement of thecenter drawer E will relieve the springs and permit the vertical slidesto rise under the action of the spiral springs to unlock the drawers.

I am aware that acabinet-desk with drawertable and bars in combinationwith pivoted inclined bar secured to a connecting-har and slide-barprovided with clasps and guide has been invented. Also I am aware of asliding drawer, a vertically-slidable rod mounted in the back of thedesk, a beveled spur, a rocking lever pivoted to the upper end of rodand fulcrumed to the top of desk. I therefore do not claim such aconstruction. Broadly, my invention relates to an improved form of thecenter drawer and also to improvements in the locking mechanism in whichthe center drawer by an independent angular movement operates thelocking device. A v

What I claim, and desire to secure by Letters Patent, is-

In a cabinet-desk having a series of drawers in each pedestal and anupper central drawer, said central drawer having rearwardly-projectinginclined sides, a horizontal bar in the path of movement of saidinclined sides, a

IOO

der the horizontal bar, Substantially as de-v scribed.
